This is worth reading from Adam Tooze, who I think wrote the best book about the GFC and the decade of crises that followed it - Crashed. As he says, the scale and speed of the economic catastrophe engulfing us is without any precedent, not even the Great Depression. Governments are responding with spenidng on a scale hitherto unseen as well. There is no going back to the old 'normal', but the politics of this moment are still up for grabs. As Lenin said, there are decades in which nothing happens, and weeks in which decades happen. We are living through those weeks.
